Allergy symptoms hub

Symptoms of allergies can manifest in many ways, depending on how you’re exposed to allergens. For example, touching an allergen might result in an itchy rash, while inhaling pollen often triggers seasonal allergy symptoms like sneezing or a runny nose. Allergy symptoms vary from person to person—you may experience one or many symptoms, or you may experience different symptoms at different times. Common symptoms include, but are not limited to:

• Skin rash or hives
• Itchy skin
• Sneezing
• Runny nose
• Cough
• Wheezing
• Itchy, watery eyes¹

The duration of allergy symptoms largely depends on your exposure to the allergen. Some symptoms may appear within minutes, while others take hours or even days to develop. Once exposure ends, symptoms typically subside within a few hours. However, certain allergic reactions, like a rash from poison ivy, can linger for weeks.¹

Yes, coughing can be a symptom of allergies, but it is also linked to other health conditions, like the common cold. If you are uncertain about the cause of your cough, it is best to consult a doctor.¹

An itchy throat can indeed result from allergies, often due to postnasal drip. This occurs when mucus drains down the back of your throat, causing irritation. A sore throat from allergies is also sometimes described as a scratchy or dry throat. Since sore throats can also stem from colds or other illnesses, it’s wise to seek medical advice if you’re unsure.²

No, allergy medications are not designed to treat cold symptoms. The treatments for these conditions aren’t the same.

For allergies:

• Monitor daily pollen counts and limit outdoor activities when levels are high.
• Shower after being outdoors to remove pollen from your skin and hair.
• Use a saline nasal rinse.
• Consult your doctor about antihistamines or nasal sprays.

For colds:

• Prioritize rest.
• Stay hydrated.
• Use throat drops or warm saltwater rinses.

• Monitor your symptoms for any changes.²

The most effective way to manage allergies is to avoid allergens, but that isn't always possible. If you can't avoid them, your healthcare provider may recommend treatments to help manage symptoms, such as antihistamines and steroid nasal sprays.¹

Yes, allergies can sometimes mimic flu-like symptoms, making it challenging to differentiate between the two. Here’s a quick comparison to help:

• Fever: Common with colds, especially in children, but not caused by allergies.

• Itchy Eyes: Rarely seen with colds but very common with allergies.

• Sore Throat: Often an early sign of a cold but less common with allergies, which can cause more of an itchy throat.

• Sneezing: A frequent symptom of both colds and allergies.

• Tiredness: Can occur with both conditions.

• Runny Nose: Common in both colds and allergies.

• Stuffy Nose: A typical symptom for both.

• Cough: More common with colds than allergies³

By understanding these distinctions, you can better identify what might be causing your symptoms and take appropriate action.
